amanda here!!! look in attachement

Answer 1

is D supposed to be H ?

Answer 2

YEA

Answer 3

and is 7m the radius?

Answer 4

i think so yea

Answer 5

then you can find any arc length by multiplying the angle in terms of radians by the radius

Answer 6

so your angle EHG is 160 degrees, in radians that is 160/180 which is 8/9ths of a radia. multiply 8/9ths by your radius and you get 56/9 m

Answer 7

so now we divide 23 by 9? or is dat the answer

Answer 8

i do not understand where 23 came from, but if your teacher or professor wants it as simplified as possible then yes divide it, but otherwise 56/9 m(eters?) should be your answer

Answer 9

divide "it" = the 56/9

Answer 10

the measure of the arc is 160 (because the angles are congruent so 80+80=160) and the way of finding arc length is above
